Anastomosis of two ends of a blood vessel using laser surgery, has light guiding instrument that directs light from a source along an optical fiber to the joint where the light is deflected outwards to weld the tissue together

摘要

Device for application of laser light for joining together two pieces of a blood vessel (54, 56) comprises a light guiding instrument (12) with an elongated optical fiber (20) that can be inserted into the internal diameter of a blood vessel and comprises light deflecting elements (28) that deflect the light from the optical fiber radially outwards to melt the tissue of the two ends of the blood vessel and weld them together.
